Problems solved by technology

[0002] Distribution network, distribution network refers to the power network that receives electric energy from the transmission network or regional power plants, and distributes it locally through power distribution facilities or to various users step by step according to voltage. The distribution network has many voltage levels and complex network structure. , a variety of equipment types, a wide range of operating points, and a relatively poor safety environment, etc.
[0003] There are relatively many safety risk factors in the distribution network, and sometimes there will be a short circuit. Once it occurs, the power transmission of some lines will be greatly affected and affect the living conditions of the surrounding residents.

Abstract

A power distribution network fault intelligent self-healing switch disclosed by the present invention comprises a switch shell and a guide rail shaft, one end of the front surface of the switch shell is rotatably connected with one end of the front surface of a front plate through a hinge, the other end of the front surface of the front plate is fixedly connected with a handle, and a first main line and a second main line are arranged on two sides of the switch shell in a penetrating manner. The first main line is of two-section type design, and a first connecting plate is arranged above a fracture. By arranging a first standby line, a second standby line, an inductance coil, an electric signal amplifier and an electromagnet, a transmission line can be switched to a standby line when a power distribution network is short-circuited, and when the power distribution network is short-circuited, the current change of the main line causes the inductance coil to generate weak current, the weak current is amplified by the electric signal amplifier to supply power to the electromagnet, and the electromagnet generates magnetism to attract the first connecting plate to switch the transmission line to the standby line.

Description

technical field [0001] The invention belongs to the technical field of distribution networks, and in particular relates to an intelligent self-healing switch for distribution network faults. Background technique [0002] Distribution network, distribution network refers to the power network that receives electric energy from the transmission network or regional power plants, and distributes it locally through power distribution facilities or to various users step by step according to voltage. The distribution network has many voltage levels and complex network structure. , a variety of equipment types, a wide range of operating points, and a relatively poor security environment. [0003] There are relatively many safety risk factors in the distribution network, and sometimes a short circuit occurs. Once it occurs, the power transmission of some lines will be greatly affected and affect the living conditions of the surrounding residents. Contents of the invention [0004] ...
